Product Details

Low Flow Rate Start Flange Type Turbine Flowmeter with LCD Display

1. Introduction

LWGYML series turbine flow meter is a new generation kind of flow meter that absorbs the advanced technologies of flow meter at home and abroad. It has been optimized and designed to have so many characteristics, such as simple structure, light weight, high precision, good repeatability,easy installation and usage.

It is widely used in the sealed pipelines which doesn’t have corrosion function on SS 1Cr₁₈Ni₉Ti, 2Cr₁₃, corundum Al₂O₃ and cemented carbide and have no fiber, particle and so on. The liquid should be less than 5*10^-6m²/s with viscosity under working temperature, if the viscosity of the liquid is more than 5*10^-6m²/s, then the flow meter can be used after calibration. If it is equipped with other display devices with special functions, it can also do quantity control, excessive alarm and so on. It is really perfect in flow measurement and energy

conservation.

2. Features

High accuracy, usually reach ±1%R,±0.5%R,or even reach ±0.2%R for high-precision type.
Good repeatability, it can reach 0.05%-0.2% in short term, if regular calibration or online calibration can get an extremely high accuracy, so it is preferred in foreign trade.
Pulse signal output, it is suitable for totalizer measurement and computer connection, no zero drift,strong capacity of resisting disturbance.
High frequency signal(3-4KHz), strong signal resolution.
Wide range, middle and big diameter can reach 1:20, and small diameter can reach 1:10.
Compact structure, easy installation and maintenance.
